CH02. Cost and Cost Structure

Presentation key message: Cost is not a number that begins in an accounting table; it is the practical price floor derived from the activities required to create and deliver customer value.

1. Learning Objectives

Be able to apply the logic of how costs arise from activities, and distinguish between Fixed Cost, Variable Cost, Direct Cost, and Indirect Cost.

2. Core Concepts

Cost is the real-world constraint that must be checked first when setting a price. Even when pricing is set strategically, Cost still remains the constraint that functions as the realistic floor for price. In other words, no matter how sophisticated the pricing strategy, if the price continually falls below Cost, the business cannot survive.

The starting point for identifying Cost is not the accounting chart of accounts but actual activities. The approach is to first list out the activities the business must actually carry out — technology development, product manufacturing, sales and distribution, workforce operation — and then calculate what costs each of these activities requires. The costs derived this way can then be read through a few classification lenses: whether they occur at a constant level regardless of production volume (Fixed Cost) or change with production/sales volume (Variable Cost), and whether they can be directly traced to a specific product or service (Direct Cost) or are spread across multiple departments/products and are difficult to attribute (Indirect Cost). A manufacturing company calculates Manufacturing Cost by summing material cost, labor cost, and manufacturing overhead, while a distribution company uses the purchase cost of goods as its baseline; adding SG&A to either brings the figure close to Total Cost.

3. Why It Matters

How the cost structure is designed changes the business strategy itself. A business with high Fixed Cost struggles to survive unless it secures a certain level of sales volume, while a business with high Variable Cost must continually verify whether enough profit per unit remains even as sales volume grows. A product with high Manufacturing Cost prompts consideration of ways to reduce unit cost, such as cutting distribution stages or increasing production volume. In this sense, cost analysis is not a mere accounting exercise but a strategic filter that forces a fresh look at customers, channels, production methods, and sales volume.

4. Framework / Logic

The logic covered in this chapter proceeds in two stages.

First, the stage of estimating cost from activities. The activities the business must carry out are listed first. Technology development incurs costs such as research personnel, prototypes, materials, technology licensing, outsourced development, equipment, and information use. Producing a product requires materials, production personnel, leasing, outsourced processing, and transport/storage/packaging costs. Sales and distribution requires market research, securing distribution channels, advertising, exhibitions, samples, and sales personnel. The more concrete the execution details of the business plan, the more concrete the cost estimate becomes.

Second, the stage of reading the costs derived this way as a structure. Accounting draws a strict distinction between Cost and Expense, but what a business planner needs is not that strict distinction but the practical perspective of grasping the “total cost required to make, distribute, and sell the product.” When that total cost is broken down along the two axes of Fixed Cost/Variable Cost and Direct Cost/Indirect Cost, it becomes clear which activities remain a burden regardless of sales volume and which activities can be attributed to a specific product.

5. Application Process

  1. List the activities the business actually carries out, grouped as technology development, production, sales and distribution, workforce, etc.
  2. List the detailed cost items required for each activity (personnel, materials, equipment, outsourcing, distribution, advertising, etc.).
  3. Classify the listed cost items into Fixed Cost / Variable Cost.
  4. Classify the listed cost items into Direct Cost / Indirect Cost.
  5. For a manufacturing company, sum material cost, labor cost, and manufacturing overhead to derive Manufacturing Cost; for a distribution company, derive the purchase cost.
  6. Add SG&A to arrive at a figure close to Total Cost.
  7. Judge whether a profit can still be left after covering these activities and costs.

6. Applying This in Pricing or the Harness

The cost structure organized in this chapter (Fixed Cost, Variable Cost, Direct Cost, Indirect Cost, Manufacturing Cost, SG&A) becomes the direct input fed into the MODE A calculation of the Pricing Harness covered in Part III of this book. The detailed calculation logic of MODE A is not covered in this chapter; here, it is only noted that precisely classifying the cost items needed for that calculation is the precondition for the later stage.

7. Practical Checkpoints

  • Did you start from actual activities rather than looking for costs in accounting accounts first?
  • Is the execution content of the business plan concrete enough that the cost estimate is equally concrete?
  • Have you identified whether the structure is Fixed-Cost-heavy or Variable-Cost-heavy?
  • Have you distinguished Direct Cost from Indirect Cost to clarify which costs are attributable to a specific product or service?
  • Have you added SG&A to Manufacturing Cost (or purchase cost) to arrive at a figure close to Total Cost?
  • Have you examined how this cost structure affects pricing decisions and judgments on channel, production method, and sales volume?

8. Key Takeaways

Cost is the realistic floor for price, and Cost is derived not from accounting accounts but from actual activities. Costs derived from activities are read by classifying them into Fixed Cost/Variable Cost and Direct Cost/Indirect Cost, and Total Cost is grasped by adding SG&A to Manufacturing Cost (or purchase cost). Designing the cost structure is not an accounting exercise but a strategic filter that changes the business strategy itself.

9. Practical Questions

  • What activities does our business actually carry out, and what costs does each activity require?
  • What is the proportion of Fixed Cost versus Variable Cost in our cost structure?
  • Have you distinguished costs directly attributable to a specific product/service from those that are not?
  • Is the structure one in which per-unit profit is actually secured as sales volume grows?
  • Can a profit still be left after covering this cost structure?
